Looking at the categories and the poll results I see a problem...

Auto oil - it's a problem. Don't use it in a cycle engine.

Back in the day it was fine to use in a cycle, but not anymore. Changes in regulations forced the oil industry to reduce the amounts of Zinc and Phosphorus (ZDDP) in oils designed for passenger cars. That in turn forced the widespread use of roller lifters. Low levels of ZDDP are only adequate for roller (non-solid) valvetrains.

ZDDP is sacrificial in the event that high pressure areas like cams/rockers aren't getting adequate oil quickly enough, and galling could occur. That can happen in any engine with a non-roller valvetrain like a cycle engine.

The inexpensive answer are diesel oils like Shell Rotella, which have safe levels. Cycle-specific oil have at least the same levels as Rotella, and often higher.

One misconception about auto oils is that they all contain "Friction Modifiers" that can make the wet clutch slip - so that's why they shouldn't be used in cycle engine. That's really not much of an issue, as only oils in the 30-grade and below have them anyway.

The REAL issue is the inadequate ZDDP levels.

Just use a diesel (EDIT: or motorcycle specific) oil and you are good.

This time? Spectro 4, 20W40.
It's dino oil but I'll be changing it once a season and that means only 2 to 3 thousand miles on it. I don't ride it below 50 degrees anyhow.

^ Finally, someone else that uses Spectro4. I use the 10w40 and change every 2000 miles. I didn't even know it came in 20w40, I knew they have 20w50.

I got it at Dennis Kirk. The local stores here didn't have anything I would want to use.

Amsoil 10W-40. Been using it since 2006 and have been changing every 10k miles. It currently has over 53k miles and still runs like a champ.

Local auto stores and truck stops always have Rotella T in 15w40.
3k miles per change since new and still rolling 13 years later with those “horrible” PH6017a Frams on it too.
No burning oil, no bursting into flames from detonated oil pumps.
Who knew?
It might give out tomorrow though. Haha

Do you live in a hot environment? I just recently picked up a 2008 500R and I live in the southwest desert. We get temps around 110F in the summers... so I was considering going that route.

I would likely run a different weight closer to winter... as we also get temps down to around 30F.

cheers!!

She’ll Rotella T6 oil, Hiflofiltro oil filter because of the nut on the top easy to remove, and the same brand air filter. Anyone have any experience with this these filterS? Never used them before, but rating and reviews were solid and it was fairly priced.
